• Bun (https://bun.sh)

Building the Server

dotnet publish -c Release -r win-x64 --self-contained true /p:PublishSingleFile=true /p:EnableCompressionInSingleFile=true

Testing the Server and Extension

1. Open GSCLSP.slnx in Visual Studio or IDE of choice
2. Setup your NuGet to build the C# server

You can do so by going to Tools -> NuGet Package Manager -> Package Manager Settings, and then going to Sources and adding nuget.org for source https://api.nuget.org/v3/index.json.

3. Set the target to Release, and then right click on the solution on the right and click Build Solution
4. Open a command prompt, and run bun install inside of the GSCLSP.Extension folder.

Now you can open VSCode in the extension source code and click F5 to test the extension. Any updates done to the server can easily be reloaded from VSCode with the extension tester.
